javascript - 未定义“createPolyglotMiddleware”

Question

我正在尝试按照此处的说明设置 redux-polyglot:https://www.npmjs.com/package/redux-polyglot

我的问题是，当我添加 const polyglotMiddleware = createPolyglotMiddleware( 部分时，我收到一条错误，告诉我它没有定义。我不知道哪里出了问题。可以有人帮忙吗？

这是我的 reducer 代码:

import { createStore, combineReducers, applyMiddleware } from 'redux';
import { polyglotReducer } from 'redux-polyglot';

const rootReducer = combineReducers({
    polyglot: polyglotReducer
});


const polyglotMiddleware = createPolyglotMiddleware(
    'ACTION_TO_CATCH',
    action => action.payload.locale,
    locale => new Promise(resolve => {
        // perform async here
        resolve({
            hello: 'bonjour',
        });
    }),
)

const store = createStore(rootReducer, {}, applyMiddleware(polyglotMiddleware));

export default store;

我认为您忘记导入createPolyglotMiddleware，请在模块顶部尝试以下操作:

import { polyglotReducer, createPolyglotMiddleware } from 'redux-polyglot';
